Answer:

x = 1; y = 3

Step-by-step explanation:

Get the unknowns on one side of the equal sign and the known numbers on the other:

EQUATION 1: y = 2x + 1 (subtract 2x from both sides)

y -2x = 1

EQUATION 2: y = 6 -3x (add 3x to both sides)

y + 3x = 6

Now we have two simultaneous equations:

y -2x = 1

y + 3x = 6

subtraction gives -5x = -5 so x = 1

Substitute x = 1 into one of the original equations to find y.

y + 3x = 6 becomes y + 3 = 6, so y = 3
