Answer:
Step-by-step explanation:
2x - 5y = 1 (times 3) 6x - 15y = 3
3x - 4y = -2 (times 2) 6x - 8y = -4
.
6x - 15y = 3
<u>6x - 8y = -4 </u> <u> </u>
-7y = 7
y = -1
.
Substitute the value of y to one of equations
2x - 5y = 1
2x - 5(-1) = 1
2x + 5 = 1
2x = 1 - 5
2x = -4
x = -2
Answer:
Just multiply the absolute values and make the answer positive. When you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative. When you divide two integers with the same sign, the result is always positive.
