7 (5a-4) - 1=14-8a

how to sovle this problem??

7 (5a-4) - 1=14-8a

Distribute the expression on the left

35a - 28 - 1 = 14 - 8a

Combine like terms

35a - 29 = 14 - 8a (-28-1 = - 29)

Get the variables on one side and the integers on the other by adding 8a to both sides and adding + 29 to both side

35a + 8a - 29 = 14 - 8a - 8a

43a - 29 + 29 = 14 + 29

43a=43

Divide both sides by 43

43a = 43

43 43

a=1

Check 7 (5x1 - 4) - 1 = 14 - 8 (1)

7 (5-4) - 1 = 14-8

7 (1) - 1 = 6

7-1 = 6

6 = 6

7 (5a-4) - 1=14-8a

Simplify both sides of the equation ...

7 (5a-4) - 1=14-8a

(7) (5a) + (7) (-4) + - 1=14+-8a (Distribute)

35a+-28+-1=14+-8a

(35a) + (-28+-1) = - 8a+14 (Combine Like Terms)

35a+-29=-8a+14

35a-29=-8a+14

Add 8a to both sides.

35a-29+8a=-8a+14+8a

43a-29=14

Add 29 to both sides.

43a-29+29=14+29

43a=43

Divide both sides by 43.

43a/43 = 43/43

a=1
