a=5
2a+5a=3 7a=3 a=3/7 or .4286
2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
a + a + a - 2a = 3a - 2a = a
x=2ab+7 x= 2(3)(5) +7 x=30+7 x=37
2a - 7 = -9 2a - 7 + 7 = -9 + 7 2a = -9 +7 2a = -2 2a/2 = -2/2 a = -2/2 a= -1
a = -7 - a So 2a = -7 and a = -3.5
The value of a is -7
a=5
2a+5a=3 7a=3 a=3/7 or .4286
2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
a + a + a - 2a = 3a - 2a = a
5a - 5 = 7 + 2a ( subtract 2a from both sides) 3a - 5 = 7 (add 5 to both sides) 3a = 12 ( divide both sides by 3) a = 4
x=2ab+7 x= 2(3)(5) +7 x=30+7 x=37
a = 26
