Because the angles are equal to each other, you can set the two quantities equal to each other and solve for x. x=20

3x+50= 6x-10
-3x= -60
X= 20

How to solve for 6x-12+2x=3+8x-15

Alecsey [184]

6x−12+2x=3+8x−15

Simplify:

6x+−12+2x=3+8x+−15

(6x+2x)+(−12)=(8x)+(3+−15)(Combine Like Terms)

8x+−12=8x+−12

8x−12=8x−12

Subtract 8x from both sides.

8x−12−8x=8x−12−8x

−12=−12

Add 12 to both sides.

−12+12=−12+12

0=0

The real numbers are the only solution we can have.

Solve for x 14 x square+7x-6

irina [24]

Answer:

x=0.450765 or x=−0.950765

Step-by-step explanation:

14x² + 7x - 6

→ Find the product, sum and factors

Product = -6

Sum = 7

Factors = No factors

→ Since there are no factors utilise the quadratic formula

$\frac{-b+-\sqrt{b^{2}-4ac } }{2a}$

→ List the values of a, b and c

a = 14

b = 7

c= -6

→ Substitute into the formula

$\frac{-7+-\sqrt{7^{2}-4*14*-6} }{2*14}$

→ Simplify

x=0.450765 or x=−0.950765

Solve the equation. <br> 4 (6 – x) + 4 = 2 (3x + 1) - 6

PtichkaEL [24]

Answer:

x = 2.4

Step-by-step explanation:

Simplify.

24 - 4x + 4 = 6x + 2 - 6

Combine like terms (24 + 4 = 28, sorry for the confusion!)

28 - 4x = 6x - 4

Add x and add 4 to both sides.

10x = 32

x = 3.2
