Answer:
(4, 1)
Step-by-step explanation:
since y=1/2x-1 in the first equation, you can substitute it into the second one:
1/2x – 1 = -x + 5
then add x to both sides:
3/2x – 1 = 5
then add 1 to both sides:
3/2x = 6
then divide both sides by the fraction to get:
x=4
then you substitute 4 into y=1/2x – 1
y = 1/2(4)-1
y = 1
so your answer is x=4 and y=1
