Hey :)
x = -10
Use the distributive property to multiply 3 by x−10
3x−30=5(2x+8)
Use the distributive property to multiply 5 by 2x+8
3x−30=10x+40
Subtract 10x from both sides
3x−30−10x=40
Combine 3x and −10x to get −7x.
−7x−30=40
Add 30 to both sides
−7x=40+30
Add 40 and 30 to get 70
−7x=70
Divide both sides by −7
x= 70/-7
Divide 70 by −7 to get −10
Hope this helps :)

Answer:
- 10
Step-by-step explanation:
Step 1:
3 ( x - 10 ) = 5 ( 2x + 8 ) Equation
Step 2:
3x - 30 = 10x + 40 Multiply
Step 3:
- 30 = 7x + 40 Subtract 3x on both sides
Step 4:
- 70 = 7x Subtract 40 on both sides
Step 5:
x = - 70 ÷ 7 Divide
Answer:
x = - 10
