Solve the simultaneous equations below grap algebraically.
1. 4x - 5y = - 20 and 2x + y = 4
2. 2x - 3y = 2 and 5x + y = 5
3. x + 3y = 12 and 2x + y = 9
4. 3x - 5y = 4 and 2x - 3y = 7
5. 2x - 3y = 12 and x + 2y = 6
6. 2x + 3y = 12 and x-y-1=0
7. x + 2y = 4 and 2x -y-3-0
8. 2y - 5x = 7 and 4x + 3y + 24 =0​

answer: what

step-by-step explanation:

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
