Question

math each equation with the correct solution
a)2x-7=9 1)10
b)1-4y=-7 2)5
c)8p+9=1 3)0
d)2(x+1)=4 4)6
e)5=3x-7 5)7
​

Answer 1

$a) \: \: \: 2x - 7 = 9$

$2x = 9 + 7$

$2x = 16$

$x = \frac{16}{2}$

$x = 8$

$b) \: \: \: 1 - 4y = - 7$

$4y = - 7 - 1$

$4y = - 8$

$y = \frac{ - 8}{4}$

$y = - 2$

$c) \: \: \: 8p + 9 = 1$

$8p = 1 - 9$

$8p = - 8$

$p = \frac{ - 8}{8}$

$p = - 1$

$d) \: \: 2(x + 1) = 4$

$2x + 3 = 4$

$2x = 4 - 3$

$2x = 1$

$x = \frac{1}{2}$

$e) \: \: 5 = 3x - 7$

$5 + 7 = 3x$

$12 = 3x$

$x = \frac{3}{12}$

$x = \frac{1}{4}$
