combine common variables
Answer:
(4x + 3)/11
Explanation:
2y -x = 3/4(-y + 1) Multiply both sides by 4
8y – 4x = 3(-y + 1) Remove parentheses
8y – 4x = -3y + 3 Add 3y to each side
11y -4x = 3 Add 4x to each side
11y = 4x + 3 Divide both sides by 11
y = (4x + 3)/11
Step-by-step explanation:
cost of 1 kg of jam = x
cost of 1 kg of butter = y
3x + 2y = 29 .....1
6x + 3y = 54 .....2
.....1 × 2 both sides of equation
6x + 4y = 58 .....3
.....3 - ......2
y = 4
replace y = 4 in 1......
3x + 8 = 29
x = 7
