y=x4−7; y=2
Y=2 (2)=x.4-7
2+4x-7
4x-7=2 get the variable alone by doing the same thing to both sides
4x=9
4x/4=9/4
y=9/4
x=9/4
Answer:
x=15
Step-by-step explanation:
3x−5+5=40+5
3x=45
Step 2: Divide both sides by 3.
3x3=453
x=15
Answer:
-7 + 8 m + 4 n thus A. is your Answer
Step-by-step explanation:
Expand the following:
-(-8 m - 4 n + 7)
-(7 - 8 m - 4 n) = -7 - -8 m - -4 n:
-7 - -8 m - -4 n
-(-8) = 8:
-7 + 8 m - -4 n
-(-4) = 4:
Answer: -7 + 8 m + 4 n
Answer:
y = -8/5
Step-by-step explanation:
Step 1: Write equation
5/8y = -1
Step 2: Solve for <em>y</em>
- Divide both sides by 5/8: y = -8/5
Step 3: Check
<em>Plug in y to verify it's a solution.</em>
- Substitute: 5/8(-8/5) = -1
- Multiply: -40/40 = -1
- Divide: -1 = -1
