Question

Can anyone help me solve these problems please? They are equations and inequalities

Answer 1

Answer:

1. -40=12x+8 : x=-4

2. -4x+2≥-6x : x≥−1

3. -11≤7x+3 : x≥−2

Step-by-step explanation:

1. Step 1: Flip the equation.

12x+8=−40

Step 2: Subtract 8 from both sides.

12x+8−8=−40−8

12x=−48

Step 3: Divide both sides by 12.

12x

12=−48

12

x=−4

3. Step 1: Flip the equation.

7x+3≥−11

Step 2: Subtract 3 from both sides.

7x+3−3≥−11−3

7x≥−14

Step 3: Divide both sides by 7.

7x

7

≥

−14
