Answer:

3x+4

Step-by-step explanation:

When simplifying expressions, you need to combine like terms. 5x and -2x combined would equal 3x. Since the 2x was negative, you needed to subtract. Next, you combine 3 and 1, which should equal 4.

When putting the expression back together, make sure you leave it in the same order as received. This would mean you would put the coefficient with the variable first, and then put the whole number.

Make sure to take the signs into account. If it is negative, you subtract, and if it is positive, you add.

Hope I helped!

In the following equation, when x=3, what is the value of y? -4x + 3y = 12

deff fn [24]

Answer:

y = 8

Step-by-step explanation:

-4(3) = -12

to get -12 to 12 you need to add 24 to -12 to make it 12.

so 3 (8) = 24

so -12 + 24 =12

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = x - 16

5y = 2x - 56

Step 2: Solve for x

Substitute in y: 5(x - 16) = 2x - 56
Distribute 5: 5x - 80 = 2x - 56
[Subtraction Property of Equality] Subtract 2x on both sides: 3x - 80 = -56
[Addition Property of Equality] Add 80 on both sides: 3x = 24
[Division Property of Equality] Divide 3 on both sides: x = 8

Step 3: Solve for y

Define original equation: y = x - 16
Substitute in x: y = 8 - 16
Subtract: y = -8
