Hello there!
3x + 5 = -2
Let's start by adding - 5 to both sides
3x + 5 - 5 = -2 - 5
3x = -7
Then divide both sides by 3
3x/3 = -7/3
x = -7/3
There is one solution for this equation.
Good luck with your studies!
5)Substituting any of the following equations; i chose bottom into top:
-2x+5=x+2
=>-3x=-3
=>x=1
Sub the x in any of the eqs to find y so
Y=1+2
=>Y=3
ANS: (1,3)
6) substituting the top equation into the bottom one:
3x+2x+4=9
=>5x=13
=>x=13/5 or 2.6
Sub the x in any of the eqs to find the y so
Y=5.2+4
=>y=9.2
ANS: (2.6, 9.2)
