Well, 1 is in the tenths place, which means it's equal to 1 tenth, or 1/10.
X=22
(X+1)+ (3x+1)= 90
4x+2=90
4x=88
x=22
You can write the two equations x = 4y - 7 and x + y = 93; substitute the value of x into the other equation
(4y - 7) + y = 93; combine like terms
5y - 7 = 93; add 7 to both sides
5y = 100; divide both sides by 5
y = 20; substitute this value into the other equation
x + 20 = 93
x = 73
So the numbers are 20 and 73
(–23) – 45 – (–98) =–23 – 45 +98=-68+98=30
