Solve for x and y: 7(y + 3) - 2(x + 2) = 14, 4(y - 2) + 3(x - 3) = 2
Solution:
Step 1: Simplify the linear equations.
7(y + 3) - 2(x + 2) = 14 --- eq(1)
4(y - 2) + 3(x - 3) = 2 --- eq(2)
Rewrite them as:
⇒ 7y + 21 - 2x - 4 = 14 or 7y - 2x = -3 --- eq(3)
⇒ 4y - 8 + 3x - 9 = 2 or 4y + 3x = 19 --- eq(4)
Let us use the elimination method to solve the equations.
Step 2: Multiply equation (3) by 3 and equation (4) by 2.
21y - 6x = - 9 --- eq(5)
8y + 6x = 38 --- eq(6)
Step 3: Add equation (5) and (6).
29y = 29
y = 1
Step 4: Substitute the value of y in equation 3.
7 (1) - 2x = -3
2x = 10
x = 5
Solve for x and y: 7(y + 3) - 2(x + 2) = 14, 4(y - 2) + 3(x - 3) = 2
Summary:
The values of x and y for the equations 7(y + 3) - 2(x + 2) = 14, 4(y - 2) + 3(x - 3) = 2 are 5 and 1 respectively.
