Answer:
x = 3
y = 2
Step-by-step explanation:
3x + 2y = 12
-2x + 3y = 5 to find the solution we will use elimination method and for that, multiply second equation with 3 and the first equation with 2
<em>2 * 3x + 2y = 12</em>
<em>6x + 4y = 24</em>
<u>3 * -2x + 3y = 5</u>
<u>-6x + 9y = 15</u> now find the sum of both equation:
<em>6x + 4y </em><u>-6x + 9y</u> = 24 + 15 add like terms
13y = 39 divide both sides by 13
y = 3 now that we found the value of y we can use this to calculate the value of x
3x + 2y = 12 replace y with 3
3x + 2*2 = 12
3x + 4 = 12 subtract 4 from both sides
3x = 9 divide both sides by 3
x = 3
First we will do -3 times everything in the parenthesis.
-3 times -4n = 12n
-3 times 30 = -90
SO,
12n - 90 = -30
+90 +90
12n = 60
divide 12 on both sides;
n = 5
This is your answer,
IF THIS HELPED, PLS GIVE ME BRAINLIEST!
S + 24 = 90
This is a one-step problem. so, all you have to do is subtract 24 on both sides:
s + 24 - 24 = 90 - 24
s = 66
Check your work:
66 + 24 = 90
90 = 90
Hope this helps!!

Answer:
X= -50
Step-by-step explanation:
Subtract 7 from both sides then multiply by 5.
X/5 =-10
5 x -10 = -50
So x= -50
