Question

can someone help me solve this I do not understand
y = 3x -4
y = 2x +5

Answer 1

Answer:

x=9 and y=23.

Step-by-step explanation:

Given:

3x-4=y

2x+5=y

Proof:

In both the equations, the RHS is the same (i.e. y), so we can equate both the equations.

3x-4=2x+5

On transposing -4 to RHS and 2x to LHS, we have,

3x-2x = 5+4

x = 9

On substituting x value in any one of the equation,

3(9)-4 = y

27-4 = y

y = 23.

Therefore, the values of x and y are 9 and 23.

Hope it helps you and you have understood.

Good Luck.
