What is the answer to 11x+4+51+2x+8=180
Digiron [165]
Hi,

Work:

Equation;

11x + 4 + 51 + 2x + 8 = 180

Collect like terms and calculate sum of positive numbers.

13x + 63 = 180

Move constant +63 to the right side and change its sign.

13x = 180 - 63

Subtract numbers.

13x = 117

Divide both sides of equation with 13.

x = 9


Hope this helps.
