-71+7
16x
-64
16 goes into -64 -4 times.
Answer would give you x
-4
To check, you could substitute -4 into the inequality
16(-4)-7
-71
-71
-71 check
16(-10)-7
-71
-167
-71 check

Answer: quit
Step-by-step explanation:
Answer:y=6.61,x=-6.46
Step-by-step explanation:
3x+7y=-26(×5)
-
5x+3y=-14(×3)
=15x+35y=-130
-
15x+9y=-42
subtracting the 2 equations =15x-15x+35y-9y=-130-(-42)
=26y=172
y=172÷26
y=6.61
substitute y in the first equation=3x+6.61=-26
3x=-26+6.61=-19.39
x=-19.39÷3
x=-6.46
