Answer:
X=3, y=-6
Step-by-step explanation:
7x+4y=-3 equation 1
-7x-5y=9 equation 2
-y=6. Add above two equations
Y=-6
solve for x by inputting y value into either equation.
7x+4(-6)=-3
7x-24=-3
7x=21
x=3
check answer by inputting x and y values into either equation
-7x-5y=9
-7(3)-5(-6)=9
–21+30=9
9=9
120 into 4 give you the right answer
Answer:
1. 8n + 4
2. 5x +13
3. X + 3
4. X - 6
5. 4x + 1
Step-by-step explanation:
1.
2n + 6 and 6n -2 so simply addition will be
2n +6 +6n -2
8n +4
2.
3x + 9 + 2x + 4
5x + 13
3.
3x + 5 - 2x -2
X +3
4.
4x + 3 - 3x -9
X -6
5.
6x + 2 - 2x -1
4x + 1
