Answer 1

Answer:

QUESTION NO 1.

Step-by-step explanation:

Let's solve your equation step-by-step.

2(x−1)=x+2

Step 1: Simplify both sides of the equation.

2(x−1)=x+2

(2)(x)+(2)(−1)=x+2(Distribute)

2x+−2=x+2

2x−2=x+2

Step 2: Subtract x from both sides.

2x−2−x=x+2−x

x−2=2

Step 3: Add 2 to both sides.

x−2+2=2+2

x=4

QUESTION NO 2.

Let's solve for s.

7−x=3x−s

Step 1: Flip the equation.

−s+3x=−x+7

Step 2: Add -3x to both sides.

−s+3x+−3x=−x+7+−3x

−s=−4x+7

Step 3: Divide both sides by -1.

−s−1=−4x+7−1

s=4x−7

Answer:

s=4x−7
