Amber Hess · Answer 1

-4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

-3 (7-2x) + 3=8x-10

(-3) (7) + (-3) (-2x) + 3=8x+-10 (Distribute)

-21+6x+3=8x+-10

(6x) + (-21+3) = 8x-10 (Combine Like Terms)

6x+-18=8x-10

6x-18=8x-10

Step 2: Subtract 8x from both sides.

6x-18-8x=8x-10-8x

-2x-18=-10

Step 3: Add 18 to both sides.

-2x-18+18=-10+18

-2x=8

Step 4: Divide both sides by - 2.

x=-4

Step-by-step explanation:

-3 (7-2x) + 3=8x-10

Step 1: Simplify both sides of the equation.

-3 (7-2x) + 3=8x-10

(-3) (7) + (-3) (-2x) + 3=8x+-10 (Distribute)

-21+6x+3=8x+-10

(6x) + (-21+3) = 8x-10 (Combine Like Terms)

6x+-18=8x-10

6x-18=8x-10

Step 2: Subtract 8x from both sides.

6x-18-8x=8x-10-8x

-2x-18=-10

Step 3: Add 18 to both sides.

-2x-18+18=-10+18

-2x=8

Step 4: Divide both sides by - 2.

-2x
