Answer:
x=8.5
Step-by-step explanation:
To solve this equation, we want to find out what x is. To do this, we need to get x by itself.
Perform the opposite of what is being done to the equation. Remember to perform everything to both sides.
4(x-5)=14
4 is being multiplied by x-5. The opposite of multiplication is division. Divide both sides by 4.
4(x-5)/4=14/4
x-5=14/4
x-5=3.5
5 is being subtracted from x. The opposite of subtraction is addition. Add 5 to both sides.
x-5+5=3.5+5
x=3.5+5
x=8.5
Let's check our solution. Plug 8.5 in for x in the original equation.
4(x-5)=14
4(8.5-5)=14
4(3.5)=14
14=14
Both sides of the equation are the same, so we know our solution, <u>x=8.5 </u>is correct.
First, you have to give each a variable. In this case, the smaller number will be x and the larger number will be y.
Next, you need to make the equations. Your equations are:
y+3x=14
x+2=y
What you're solving for is y because the questions asks what the larger number is.
Then, substitute. It will be this after substituted:
x+2+3x=14
Combine like terms.
4x+2=14
Subtract by 2 on both sides.
4x=12
Divide by 4 on both sides.
x=3
^This what your smaller number is but you can easily find what y (the larger number) is. Substitute x into the other equation, which is basically adding 2 to 3.
y=5
