Solve in(5x+7)=8 round to the nearest thousandth

Ivan

Answer:

$x=\frac{1}{5}$

$x=0.2$

Step-by-step explanation:

$(5x+7)=8$

$5x+7=8$

Subtract 7 from both sides.

$5x+7-7=8-7$

Simplify.

$5x=1$

Divide both sides by 5.

$\frac{5x}{5} =\frac{1}{5}$

Simplify.

$x=\frac{1}{5}$

7x + 8y = 25 9x + 10y =35 elimination method please

djverab [1.8K]

$7x +8y = 25 ~~~....(i)\\\\9x +10y = 35~~~ ....(ii)\\\\\text{Multiply equation (ii) by}~ \dfrac 79 ~ \text{and do (ii) - (i):}\\\\\dfrac 79 (9x +10y) - (7x +8y) = \dfrac 79 (35) - 25\\\\\\\implies 7x +\dfrac{70y}9 - 7x -8y = \dfrac{245}9 -25\\\\\\\implies - \dfrac{2y}9 = \dfrac{20}9\\\\\\\implies -2y =20\\\\\implies y =-10\\\\\text{Substitute}~ y = -10~ \text{in equation (i):}\\\\\\7x +8(-10) = 25\\\\\implies 7x = 25 +80\\\\\implies 7x = 105 \\\\\implies x =15\\\\$

$\\\text{Hence}~ (x,y) = (15,-10)$
