What number does x stand for in this equation?<br><br> -7x + 6=27
AURORKA [14]
⓵ You need to solve the left side first in order to isolate the × and find it’s value :

-7× + 6 = 27
-6 -6
↓

-7× = 21
÷-7 ÷-7

↓

× = -3

If you find it too difficult to divide a number by a negative, just divide 21 by 7 and always remember that when dividing, when the signs are different the answer is negative. So knowing that you could just divide 21 by 7, which is 3, and add a negative sign in front!


I hope this helped, if there’s anything let me know! ☻

Illusion [34]
(-6,20) \\&#10;x=-6 \\ y=20 \\ \Downarrow \\&#10;20 \stackrel{?}{=} (-6)^2+2 \times (-6)-4 \\&#10;20 \stackrel{?}{=} 36-12-4 \\&#10;20 \stackrel{?}{=} 20 \\&#10;20 = 20 \\&#10;\hbox{the point is on the graph}

(-4,4) \\&#10;x=-4 \\ y=4 \\ \Downarrow \\&#10;4 \stackrel{?}{=} (-4)^2+2 \times (-4)-4 \\&#10;4 \stackrel{?}{=} 16-8-4 \\&#10;4 \stackrel{?}{=} 4 \\&#10;4 = 4 \\&#10;\hbox{the point is on the graph}

Both points are on the graph.

At first Divide the figure into two rectangles, I and Il

Area of figure l is ~

  • \sf24 \times (40 - 30)

  • \sf24 \times 10

  • \sf240 \:  \: ft {}^{2}

Area of figure ll is ~

  • \sf 18 \times 30

  • \sf540 \: ft{}^{2}

Area of whole figure = Area ( l + ll )

that is equal to ~

  • \sf240 + 540

  • \sf780 \:  \: ft{}^{2}
