Simplifying
10y + 4 = 2x

Reorder the terms:
4 + 10y = 2x

Solving
4 + 10y = 2x

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-4' to each side of the equation.
4 + -4 + 10y = -4 + 2x

Combine like terms: 4 + -4 = 0
0 + 10y = -4 + 2x
10y = -4 + 2x

Divide each side by '10'.
y = -0.4 + 0.2x

Simplifying
y = -0.4 + 0.2x

Apples cost $0.75 per pound and bananas cost $1.05 per pound.
dedylja [7]

Answer:

The baker bought 8 pounds of apples and 4 pounds of bananas.

Step-by-step explanation:

a+b=12.

0.75a+1.05b=10.20

First, multiply 2 my 10.

75a+105b=1020.

Then multiply 1 by 75.

75a+75b=900.

Then subtract.

75a+105b=1020

75a+75b=900.

75a-75a+105b-75b=1020-900

30b=120

b=4

Substitute into (1)

a+4=12

a=8.

Hope this helps :)
