Answer:
(7/8,23/4) or (0.875,5.75)
x=7/8 or 0.875
y=23/4 or 5.75
Explanation:
2x+4=y
4y-18=5
substitute the value of y into an equation
4(2x+4)-18=5
multiply 4 to 2x and multiply 4 to 4
8x+16-18=5
subtract 16 to 18
8x-2=5
add 2 to 5
8x=7
divide both sides by 8
x=7/8 or 0.875
substitute the value of x into an equation
4y-18=5
add 18 to 5
4y=23
divide both sides by 4
y=23/4 or 5.75
(7/8,23/4) or (0.875,5.75)
