Step-by-step explanation:
Let's solve your equation step-by-step.
3x+5+5x+7=180
Step 1: Simplify both sides of the equation.
3x+5+5x+7=180
(3x+5x)+(5+7)=180(Combine Like Terms)
8x+12=180
8x+12=180
Step 2: Subtract 12 from both sides.
8x+12−12=180−12
8x=168
Step 3: Divide both sides by 8.
8x /8 = 168 /8
x=21
