3x + 1 + 5x = 7 +15 + 7x

Move unknown terms to the left of the equal with changed sign and the known terms to the right of the equal with changed sign.

3x + 5x - 7x = 7 + 15 - 1

x = 21

Combine like terms on each side of the equation...

8x+1=7x+22  subtract 1 from both sides

8x=7x+21  subtract 7x from both sides

x=21

14=3(x-2)+5<br>How can I solve this equation?​
daser333 [38]
1. distribute the 3 into the variable and number in the equation
to do this..
2. multiply 3 by x (obtain the answer of 3x)
3. multiply 3 by -2 (obtain the answer of -6)
4. you now have the equation of ‘14 = 3x-6+5’
5. subtract 6 from 5 (obtain the answer of -1)
6. you now have the equation of ‘14 = 3x-1’
7. add one to both sides (cancel out the negative one and make the opposite side of the equation 15 instead of 14)
8. you now have the equation of ‘15 = 3x’
9. divide both sides by 3 (15 and x)
FINAL ANSWER
x = 5
hope this helps:)
