Step-by-step explanation:
Answer:
x = -2, y=1
Step-by-step explanation:
x-7y=-9---------------------equation 1
-x+8y=10-------------------equation 2
From equation 1, make x the subject of formula
x=7y-9----------------------equation 3
substituting x=7y-9 in equation 2,
-(7y-9)+8y=10
Expanding bracket
-7y+9+8y=10
Collecting like terms
8y-7y=10-9
y=1
substituting y=1 in 3
x=7(1)-9
x=7-9
x=-2
3 - (7a + 1) =
3 - 7a - 1 =
-7a + 2 <===
Answer:
125
Step-by-step explanation:
-2b=44 divided both sides by -2
-2b/-2=44/-2 -2 on the left side cancels out
b= -22 is your answer
