Answer:
x = 5
Step-by-step explanation:
Step 1: Write equation
5x - 7 = 18
Step 2: Solve for <em>x</em>
- Add 7 to both sides: 5x = 25
- Divide both sides by 5: x = 5
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
5(5) - 7 = 18
25 - 7 = 18
18 = 18
Answer:
X=2, y=8
Step-by-step explanation:
Y=-x+10 equation 1
y=2x+4 equation 2
-x+10=2x+4. Substitute y of first equation into 2nd equation
-x-2x+10=4
-3x=4-10
-3x=-6
x=2
solve for y by inserting x value into either equation
y=-x+10
y=-2+10
y=8
check answer
y=2x+4
8=2(2)+4
8=4+4
8=8
I like the first one and tje third one
