Please help solve all of these- 1. Solve the equation for y: 10x + 5y = 15

2. Solve the equation for y: x - 2y = -8

3. Solve the formula for H: V = LWH

4. Solve the formula for b: A = 1/2bh

3−y

2. 8

4.2bh

Step-by-step explanation:

5(2x+y)=15

2 Divide both sides by 55.

2x+y=\frac{15}{5}2x+y=

5

15

3 Simplify  \frac{15}{5}

5

15

  to  33.

2x+y=32x+y=3

4 Subtract yy from both sides.

2x=3-y2x=3−y

5 Divide both sides by 22.

x=\frac{3-y}{2}x=

2

1. 3−y

2. 8

2.Add 2y2y to both sides.

x=-8+2yx=−8+2y

2 Regroup terms.

x=2y-8x=2y−8

she gotta workk that a 2
