Question

solve each of the following equation 7x+2=-19 , 3x-1/3=5 , 5x-4=21 , -7x=21 , 18- 7x=-3​

Answer 1

Step-by-step explanation:

$(1)\: \: 7x = 19 + 2$

$7x = 21$

$x = 21 \div 7$

$x = 3$

$(2) \: 3x = 5 + 1 \div 3$

$3x = 15 + 1 \div 3$

$3x = 16 \div 3$

$9x = 16$

$x = 16 \div 9$

x = 4/3.

$5x = 21 + 4$

$5x = 25$

$x = 25 \div 5$

$x = 5$

$(4) \: x = 21 + 7$

$x = 28$

$(5) \: 18 + 3 = 7x$

$21 = 7x$

$x = 21 \div 7$

$x = 3$
