Answer:
y = 7
Step-by-step explanation:
1) Substitute X with 1
9 ( 1 ) - 2y = - 5
2) Simplify 19×1 to 9
9 − 2y = −5
3) Subtract 9 from both sides
−2y = −5 − 9
4) Simplify −5−9 to −14
−2y = −14
5) Divide both sides by −2.
y = -14 / -2
6) Two negatives make a positive.
y = 14 / 2
7) Simplify 14 / 2 to 7
y = 7
Answer:
y = 7
Step-by-step explanation:
9x - 2y = -5
Put x = 1 in for x.
9(1) - 2y = -5
Multiply 9*1, which equals 9.
9 - 2y = -5
Subtract 9 on both sides.
-2y = -5 - 9
Combine -5 and -9, which equals -14.
-2y = -14
Divide by -2 on both sides.
This means...
y = 7.
